TECHNICAL FIELD

[0001] The present invention relates to thermoplastic containers and lids, and more particularly to a device for holding and stacking thermoplastic lids.

BACKGROUND OF THE INVENTION

[0002] The use of containers for the storage of items is well known. Such containers are used to store a variety of articles, from food to general household items including everything from craft supplies to children's toys. Generally, such containers can be characterized by shape and size. Containers that do not include a lid require a separate sealing member, such as a plastic wrap or aluminum foil. Often, the plastic wrap or aluminum foil is loose or jostled during movement of the container, and hence, the container is usually not properly sealed or closed to prevent contents therein from spilling. Containers that include lids overcome this problem.

[0003] As is well known, many different types and sizes of container lids exist. When such container lids are placed together in a confined space, such as a cupboard, cabinet, drawer, shelf, refrigerator, or the like, a disorganized condition can develop, preventing a user from easily locating a container lid of a particular size and shape. Further, as a user is attempting to locate a particular container lid, other items may be jostled, thereby causing a container lid or one or more of the items to fall off a supporting surface to the floor, resulting in breakage of the items and/or spilling of contents and/or lost container lids. Still further, when container lids are stacked on top of each other in an unconfined location, the container lids tend to slide out of the stacked configuration and into a disorganized state making it difficult to locate the proper size and/or shaped container lid.

[0004] Staver U.S. Pat. No. 3,192,894 discloses a support for an article. The support includes a back surface for attachment to a vertical surface and a surface having a single opening to facilitate engagement of the article in cooperation therewith. A stem portion of the article is placed in the opening for suspension therefrom.

[0025] Referring now to FIGS. 1-4, a first embodiment of a holding device 30 of the present invention includes a first wall 32 and a second wall 34 joined to and integral with the first wall 32 at a joint portion 36. Each of the first and second walls 32, 34 has a width W1 and a length L1 (FIGS. 1 and 3). The length L1 is preferably between about 3.5 inches (88.9 mm) and about 15.0 inches (381 mm), and more preferably between about 4.25 inches (107.95 mm) and about 8.0 inches (203.2 mm), and most preferably about 4.625 inches (117.475 mm). Further, the width W1 is preferably between about 3.0 inches (76.2 mm) and about 15.0 inches (381 mm), and more preferably between about 3.75 inches (95.25 mm) and about 8.0 inches (203.2 mm), and most preferably about 4.240 inches (107.696 mm). The width W1 could optionally be greater depending on the preferred capacity of lids of the holding device 30. Also optionally, the length L1 may be greater depending on the size of lids to be held in the holding device 30. Although the first and second walls 32, 34 are shown as having the same dimensions, this need not be the case. The holding device 30 is preferably manufactured as a single piece, but may be manufactured as separate pieces and assembled by the manufacturer or by the consumer.

[0026] The first and second walls 32, 34 are disposed at an angle 41 with respect to one another. A first connecting portion 38 joins the first and second walls 32, 34 at first and second edge portions 40 a, 40 b of the first and second walls 32, 34, respectively, and extends over (i.e., spans) the angle 41. Preferably, but not necessarily, the angle is 90 degrees or less, but may be any angle, preferably one less than 180 degrees. The first connecting portion 38 is preferably polygonal in shape and is preferably rectangular, square-shaped, or triangular-shaped, (or other polygonal shape) but may also be circular, oval-shaped, or any other regular or irregular shape. A second connecting portion 42 joins the first and second walls 32, 34 at third and fourth edge portions 40 c, 40 d of the first and second walls 32, 34, respectively. The second connecting portion 42 is preferably the same shape as the first connecting portion 38, but may instead have a shape different from the first connecting portion 38. The first and second connecting portions 38, 42 are optional, but their primary purpose is to help prevent the lids from falling out of the holding device 30. Secondary and tertiary purposes of the connecting portions 38, 42 are to stabilize the holding device 30 and to connect the holding device to a surface.

[0027] In a preferred embodiment, as seen in FIGS. 1-4, the first and second connecting portions 38, 42 are both of the same size and are both generally square-shaped. A width W2 and a length L2 of the connecting portions 38, 42 are preferably between about 1.5 inches (38.1 mm) and about 5.0 inches (127 mm), and more preferably between about 2.250 inches (57.15 mm) and about 3.250 inches (82.55 mm), and most preferably about 2.750 inches (69.85 mm). It should be noted that the connecting portions 38, 42 can be any size depending on the size of the first and second walls 32, 34 and the size of lids to be held in the holding device 30.

[0028] Preferably, one or both of the first and second connecting portions 38 and 42 include means for mounting the holding device 30 to a horizontal surface 43 (FIGS. 1, 5 and 6). Alternatively, the holding device 30 may be placed on a horizontal surface 43 a seen in FIG. 4. As seen in the embodiment of FIGS. 1 and 2, the first connecting portion 38 includes at least one and preferably at least two mounting holes 39 a, 39 b. Further, mounting holes 39 may be placed at any location on the connecting portions 38 and/or 42. One or both of the first and second connecting portions 38 and 42 may also or alternatively include other mounting means including, but not limited to, hook and loop (i.e., Velcro) fasteners, double sided tape (FIG. 9), an adhesive, or the like, disposed on an outside surface 41 of the first and/or second connecting portions 38 and 42.

[0029] As seen in FIGS. 1 and 3, the first and second walls 32, 34 include first and second cutout portions 44, 46, respectively. The cutout portions 44, 46 are preferably step-shaped, but may also be any shape including, but not limited to, square-shaped, rectangular-shaped, triangular-shaped (or any other polygonal shape), circular-shaped, oval-shaped, or any other regular or irregular shape. Preferably, the step-shaped cutout portions 44, 46 are generally centered between the first and second connecting portions 38, 42 and include first and second base portions 48 a, 48 b that are perpendicular to one another. The step-shaped cutout portions 44, 46 further include step sections 50 a-50 c that are perpendicular to the first base portion 48 a and step sections 50 d-50 f that are parallel to the first base portion 48 a.

[0030] Lids of identical or different shapes and sizes are disposed in the holding device 30 such that each lid rests against both of the second base portions 48 b and both of the step sections 50 a, or both of the step sections 50 b, or both of the step sections 50 c. When disposed therein, the cutout portions 44, 46 allow the lids to protrude therethrough such that any suitably shaped and/or sized lid can be held by the holding device 30. It should be noted that the cutout portions 44, 46 are preferably (although not necessarily) substantial mirror images of one another and that the portions 44, 46 are disposed sufficiently close to one another to properly support the particular lids in question. The main purpose of the cutout portions 44, 46 of the present invention is to eliminate the need for a fully enclosed container to hold the lids, thereby reducing the amount of needed material for the holding device 30.

[0031] Each of the step sections 50 d and 50 e includes a divider 52 a, 52 b extending generally parallel to the portions 38 and 42 at the respective step section 50 d or 50 e.
